Detailed Description of the Invention

In a modular kitchen with multiple cooling modules, the cooling system for cooling the modules is a challenging problem. The simplest approach would be to have individual complete cooling systems for each module. In the early stages of modularity for residential kitchens, this could be the approach taken, especially when modular refrigeration product choices are few and economies of scale are not available. However, as modularity becomes more of a current trend and kitchen designs begin to incorporate modular refrigeration products with appropriate infrastructure, it will become desirable to have a unique central cooling system from the perspective of cost, manufacturing and efficiency power. Consumers will be primarily interested in the energy efficiency, cost, flexibility and expandability offered by a modular refrigeration appliance system with less concern about central cooling technology to support the modular system.

According to the invention, a modular home appliance system can be provided for a residential kitchen and other locations associated with a home that may include a central cooling unit for some or all of the cooling modules that a consumer may wish to include in your kitchen, at the time of construction or for expanding or changing cooling modules over time, as needs or desires change. A modular kitchen could allow consumers to select multiple refrigeration modules adapting to their lifestyles in the best way with the ultimate flexibility in their kitchens and kitchens fully customizable with modular appliances not only for refrigeration, but also for food preparation and cleaning the kitchen. According to the invention, a central cooling unit of single variable capacity can be provided, which is capable of combining the need for cooling with the aggregate thermal load of the cooling modules. The central cooling unit can be arranged to operate continuously by controlling the volume of the cooling medium being directed to each cooling module, so that each module is cooled to a temperature selected by the user and maintained at the desired temperature accurately. The cooling medium can be cold air, a coolant or a liquid cooler, such as a solution of ethylene glycol and water. The central cooling unit can be a vapor compression system, but it is not limited to that. If a central cooling unit is a vapor compression cooling system, the central cooling unit may have a variable capacity compressor capable of handling the cooling load of multiple cooling module products. Refrigeration module products may include freezer refrigerator modules on top, freezer freezer modules underneath, refrigerator and freezer modules having freeze compartments on top and freeze underneath in various configurations that may include, but are not limited to to built-in, stackable, under counter or drawer configurations. Also, the refrigeration module products could include specific purpose modules, such as ice maker units, air-conditioned wine cellar and bar counter refrigerator. In addition, conventional refrigeration products having a complete refrigeration system can be combined with a modular refrigeration appliance system according to the invention. For example, one or more freezer freezer units from below can be combined with a modular refrigeration appliance appliance arranged for a plurality of freezer refrigerator modules above fresh food. As will be described in more detail below, a hybrid approach can be an energy-efficient approach to the provision of cooling for modular products, since the central cooling unit can operate under more favorable cooling cycle conditions, since that a very cold cooling medium, ie below -32 ° C (0 ° F) would not be required.

Turning to Figure 1, in an embodiment of the invention, illustrated schematically, the cooling modules 20 and 22 can be connected in a system of home appliance refrigeration that can include a central cooling unit 10. In the illustrated mode in Figure 1, two cooling modules 20, 22 are illustrated. According to the invention, more than one or more than two refrigeration modules can be provided in the home appliance refrigeration system, as desired, and although two or three refrigeration modules are included in the modes shown, it should be understood that they include the possibility of one or more of two or three cooling modules within the scope of the invention. In addition, the home appliance refrigeration system can be arranged to allow an expansion of the home appliance refrigeration system subsequent to the initial installation by adding additional cooling modules, as the user's needs change over time requiring new heating modules. cooling or additional. In practice, cooling modules 20, 22 can be installed in a residential kitchen and / or in adjacent or adjacent rooms, such as a large room, a bar, a recreation room and / or other locations associated with a home. The central cooling unit 10 can be installed in a nearby location, such as a basement, a utility room, in the garage, in the yard or, if desired, in the kitchen in the vicinity of some or all of the refrigeration appliance modules , depending on the style of dwelling and whether a basement or crawl space is available or is desired for installation of the central cooling unit 10. The cooling modules 20, 22 can be independent or built-in modules and can be general purpose refrigerator or freezer modules or they can be special purpose modules, such as an ice maker or an air-conditioned cellar. Refrigeration modules 20, 22 may take the form of a conventional refrigerator or freezer cabinet having a hinged door, or may take the form of a refrigerator drawer appliance, as shown in co-pending non-provisional order N9 11 / 102,321, filed on April 8, 2005, fully incorporated herein by reference.

The cooling module 20 can have an insulated cabinet 24 and an insulated door 25 that can be hinged to the insulated cabinet 24 for the selective opening and closing of an opening 28 in the insulated cabinet 24. The cooling module 22 can have a insulated cabinet 26 and an insulated door 27 that can be hinged to the insulated cabinet 26 for the selective opening and closing of an opening 29 in the insulated cabinet 26. Those skilled in the art will understand that insulated doors 25 and 27 can be provided with a suitable handle, not shown, to facilitate the opening and closing of insulated doors 25 and 27. Cooling modules 20 and 22 can each have a heat exchanger 30 positioned in isolated cabinets 25 and 26. Similarly, cooling modules 20 and 22 can each have a variable speed heat exchange fan 32 positioned for air circulation (illustrated by air flow arrows 38) over the respective heat exchangers 30 and through the respective cooling modules 20, 22. Those skilled in the art will appreciate that a single speed fan can be used instead of a variable speed fan 32. The cooling modules 20, 22 can also have a temperature sensor 34 arranged for detecting the temperature inside the cooling modules 20, 22. The temperature sensor 34 can be a thermistor or another temperature detection mechanism or device well-known electronic or mechanical Temperature selectors 36 can be provided for each of the cooling modules 20, 22 to allow the user to select the operating temperature for the respective cooling modules 20, 22. Although the temperature selectors 36 are illustrated schematically spaced from the cooling modules 20, 22, those skilled in the art will understand that the temperature selectors 36 can be located on each of the cooling modules 20, 22, as is well known in the art, or could be centrally located, if desired. The temperature selectors 36 may comprise a well-known mechanical or electronic selector mechanism, to allow a user to select an operating temperature for the respective cooling modules 20, 22.

The home appliance refrigeration system schematically illustrated in Figure 1 also includes a central cooling unit 10. The central cooling unit 10 can include a variable speed compressor 12, a condenser 14 and an expansion device 18 connected to a refrigeration circuit with a cooled liquid evaporator 40. A variable speed condenser fan 16 can be provided for air circulation through the condenser 14. The cooled liquid evaporator 40 can be a shell and tube evaporator also known as a secondary loop evaporator. The expansion device 18 can be an expansion device with feedback arranged to control the flow of refrigerant through the expansion device 18, based on the thermal load in the home appliance refrigeration system. The central cooling unit 10 can be connected to the cooling modules 20, 22 with insulated ducts 42 forming a cooling medium circuit for transporting liquid refrigerant from the cooled liquid evaporator 40 to the heat exchangers 30 and from the heat exchangers 30 for the cooled liquid evaporator 40. The liquid refrigerant 12, not shown, contained in the cooled liquid evaporator 40, insulated ducts 42 and heat exchangers 30 can be circulated by a pump 44 which can be a variable speed pump. In addition, each refrigeration module can have a valve 46 for controlling the flow of liquid refrigerant to the heat exchanger 30. Valves 46 can be on-off valves to allow or prevent a flow of liquid refrigerant through the heat exchanger 30 to a refrigeration module. Those skilled in the art will appreciate that if a single speed heat exchange fan 32 is used in a cooling module 20, 22, an adjustable valve 46 can be used to control the amount of liquid refrigerant flowing into a heat exchanger 30, although it may be more energy efficient to use a variable speed heat exchange fan 32, a variable speed pump 44 and an on-off valve 46 for temperature control in the respective cooling modules 20, 22. The central cooling unit 10 can also have a microprocessor-based controller 50 having a first portion 52 that can be arranged for controlling the operation of the central cooling unit 10 and a second portion 54 arranged for controlling the volume of liquid refrigerant directed to the respective cooling modules 20, 22. A control circuit 56 can be provided for connecting temperature sensors 34, temperature selectors 36, variable speed compressor 12, variable speed condenser fan 16, expansion device 18, pump 44, valves 46 and heat exchange fans 32 with controller 50. Thus, a home appliance refrigeration system according to the invention is illustrated in Figure 1 as a distributed cooling system that can have a vapor compression condensing unit of variable capacity and a secondary loop using a liquid evaporator network. cooled. An example of a liquid refrigerant that can be used is a DYNALENE HC heat transfer fluid, a water-based organic salt that is non-toxic, non-flammable with low viscosity, although those skilled in the art understand that other liquid refrigerant solutions , such as a solution of ethylene glycol and water, can be used as desired.

According to the invention, the central cooling unit 10 may be operating continuously, so that a liquid cooled to a temperature suitable for obtaining the lowest selected temperature in the cooling appliance system is continuously circulated in the insulated ducts 42 that form a cooling medium circuit for the cooled liquid evaporator 40 for the cooling modules 20, 22.

The cooling modules refrigeration 120 and 326 can be independent or built-in modules and can be general purpose refrigerator, freezer or special purpose modules. Refrigeration modules 120 and 326 can be located in a residential kitchen or other locations associated with a home, as desired.

Similarly, the cooling module 120 can be similar to the cooling module 120 shown in Figure 3 and, therefore, will use the same reference numbers as the cooling module 120 in Figure 3. As mentioned above, the cooling unit Central 110 may be located in a remote location of a residential kitchen or in the vicinity of a residential kitchen, as desired, as those skilled in the art will understand.

According to the invention, other cooling modules and / or 5 satellite stations and home appliance refrigeration modules, as described above, can be combined with the central cooling unit 110, in addition to the cooling modules 120 and 326 illustrated in Figure 11.0 cooling module 120 is described in detail above and, therefore, will not be described in detail again in relation to Figure 11.

The insulated door 330 can be provided with a suitable handle, not shown, to facilitate the opening and closing of the insulated door 330. Those skilled in the art will understand that two insulated doors can be provided for independently closing compartments 331 and 332, if desired. Cooling module 326 may include a cooling module evaporator 336 and a cooling module evaporator fan 338. The cooling module evaporator fan 338 can be a single speed fan or, if desired, it can be a variable speed fan.

An expansion device 138 can control the flow of refrigerant to the cooling module 326. The expansion device 138 can be an expansion device with feedback arranged to control the flow of refrigerant through the expansion device 138. The cooling module 326 it may have a temperature sensor 134 and a temperature selector 136, as described above, for each compartment 331 and 332. Temperature sensors 134, temperature selectors 136 and expansion device 138 can be connected to controller 15 0 via control circuit 156, as described in detail above. Also, as described in detail above, temperature selectors 136 may be located on cooling modules 120 and 326 or may be part of a central user interface, as is well known and described above. The cooling module evaporator 336 can be connected to refrigerant lines which can be the isolated supply and return ducts 142 and 144 leading to the central cooling unit 110.

Cooling module 326 can still employ a cascade cooling system to cool compartment 332. For example, compartment 332 can be operated as a freezer compartment underneath and compartment 331 can be operated as a refrigerator compartment. of freezing on top. In case it is also desired that the cooling module 120 operates as a freezing refrigerator compartment on top, the central cooling unit 110 can be operated to provide refrigerant cooled sufficiently to cool the cooling module evaporators 130 and 336 for a temperature to produce freezing temperatures above in cooling module 120 and in compartment 331 of cooling module 326. The operation of the central cooling unit 110 to produce freezing temperatures from above allows the compressor 112 to operate at higher refrigerant evaporation pressures, lower refrigerant condensation pressures and therefore may require less energy for operation of the refrigerant. central cooling unit 110. Thus, when a distributed household appliance system has primarily freezer refrigerator modules above, it can be energy efficient and cost effective to use cascade cooling to obtain the desired freezing temperatures below in compartments that are you want them to operate at freezer temperatures underneath.

The cascade cooling system can be a thermoelectric cooling system 340, as illustrated in the cooling module 326. The alternative cascade cooling systems, described below 52, can be used in combination with the cooling module 326 in place of the system thermoelectric cooling system 340. The thermoelectric cooling system 340 can be connected to controller 150 via control circuit 156. The thermoelectric cooling system 340 can be a well-known thermoelectric device that can include a thermoelectric module 342 combined with heat sink enclosures 344 and 346 on opposite surfaces of the thermoelectric module 342. A heat sink enclosure 346 can be positioned in heat exchange communication with compartment 331 and the other heat sink housing 344 can be positioned in heat exchange communication with compartment 332. The thermoelectric cooler 340 may also have a circulation fan 348 for circulating air in compartment 332 over the heat sink housing 344. Although a circulation fan 348 is illustrated in compartment 332, those skilled in the art will understand that a circulation fan can be used with respect to both or neither of the heat sink housings 344 and 346, if desired. When a voltage is applied to the 342 thermoelectric module, a surface becomes cold, absorbing heat from the heat sink enclosure in contact with the cold surface, and the opposite surface becomes hot, releasing heat into the heat sink enclosure. in contact with the hot surface. Thus, when the appropriate polarity voltage is applied to the thermoelectric module 342, the heat sink envelope 344 can become cold and the circulation fan 348 can circulate cooled air through the heat sink envelope 344 through compartment 332. Meanwhile, the heat released by the heat sink enclosure 346 heats the compartment 331, the heat of which can be absorbed by the cooling module evaporator 336 and transferred to the central cooling unit 110. An appropriately sized thermoelectric cooler can easily reduce the temperature in compartment 332 by 20 ° C in relation to compartment 331, and can therefore cool compartment 332 for freezer freezer temperatures below, compared to freezer refrigerator temperatures by up in the compartment

331. Thus, compartment 332 can be cooled based on the temperature selected for compartment 332 by the temperature selector 136 for compartment 332. If desired, thermoelectric module 342 can be energized with an opposite polarity voltage to make the thermoelectric module provide heat to compartment 332 by drawing heat from compartment 331. Thus, the operation of the thermoelectric module 342 can allow a user to use compartment 332 for heating the contents of compartment 332, as well as for defrosting frozen articles, if desired. Controller 150 can be arranged to operate thermoelectric module 342 to heat compartment 332, when temperature selector 136 for compartment 332 is set for heating and / or defrost regulation. When thermoelectric module 342 is set to heat compartment 332, the heat removed from compartment 331 will cool compartment 331 and reduce the cooling load of compartment 331.

Turning to the schematic Figure 12, in another embodiment of the invention, a plurality of cooling modules 20 and 350 can be connected in a distributed household appliance system that can include a central cooling unit 10. The cooling modules refrigeration 20 and 350 can be independent or built-in modules and can be general purpose refrigerator, freezer or special purpose modules. Refrigeration modules 20 and 350 can be located in a residential kitchen or other locations associated with a home, as desired. The central cooling unit can be similar to the central cooling unit 10 illustrated in Figure 1 and, therefore, will use the same reference numbers as the central cooling unit 10 illustrated in Figure 1. Similarly, the cooling module 20 can be similar to the cooling module 20 shown in Figure 1 and, therefore, will use the same reference numbers as the cooling module 20 in Figure 1.

The cooling module 20 is described in detail above and, therefore, will not be described in detail again in relation to Figure 12. Similarly, the central cooling unit 10 is described in detail above and, therefore, will not be described in detail again in relation to Figure 12. The cooling module 350 may include a cascade cooling system. The cooling module 350 may have an insulated cabinet 352 and insulated doors 353 and 354 that can be hinged to the insulated cabinet 352 for the selective opening and closing of compartments 356 and 357 formed in insulated cabinet 352 by the insulated compartment separator 355 Insulated doors 353 and 354 can be provided with a suitable handle, not shown, to facilitate the opening and closing of insulated doors 353 and 354.

As described above, the central cooling unit 10 can include a secondary loop evaporator 40 arranged to supply cooled liquid refrigerant to the cooling modules. Although a secondary loop cooling system can produce freezing storage temperatures from below, such cooling systems operate most efficiently when arranged to provide freezing storage temperatures from above. Therefore, when a distributed household appliance system includes a secondary loop using a cooled liquid refrigerant, it can be energy efficient and cost effective to use cascade cooling to obtain the desired freezing temperatures below in refrigeration compartments. freezing freezer underneath.

The cascade cooling system for the cooling module 350 can be a thermoelectric cooling system 340 similar to the thermoelectric cooling system 340 illustrated in the cooling module 326 in the form of Figure 11.

Therefore, the thermoelectric cooling system 340 illustrated in Figure 12 will employ the same reference numbers as in Figure 11 and the operation of the thermoelectric cooling system will not be explained in detail again in relation to Figure 12. A cooled liquid refrigerant circulating through of the heat exchanger 30 in the compartment 356 can carry the heat released by the heat sink housing 346 to the central cooling unit 10. Thus, compartment 357 can be cooled regardless of the temperature in compartment 356, based on the temperature selected for compartment 357 by the temperature selector 36 for compartment 356. Also, as described above, the thermoelectric cooling system 340 can provide temperatures of lower storage in compartment 357 than can actually be obtained in compartment 356 based on the cooling provided by the cooled liquid refrigerant.

The cooling module 360 may include an air inlet 93 leading from the insulated ducts 92 and an air outlet 95 leading in a similar manner to the insulated ducts 92 which are in communication with the evaporator 90. Air inlets 93 and air outlets 95 form the apparatus for receiving the cooling medium, cooled air, in cooling modules 72 and 360, as described above in detail. A baffle 96 can control the flow of cooled air to the cooling module compartment 366 360. The baffle 96 can be adjustable between open and closed to vary the control of the cooled air flow to the 366 compartment. The cooling module 360 can have temperature sensors 84 and temperature selectors 86, as described above for each compartment 366 and 367. Temperature sensors 84, temperature selectors 86 and deflector 96 can be connected to controller 100 via the control circuit 106, as described in detail above. Also, as described in detail above, temperature selectors 86 may be located on cooling modules 72 or 360 or may be part of a central user interface, as is well known and described above.

The cascade cooling system for the 360 cooling module58 can be a thermoelectric cooling system 340 similar to the thermoelectric cooling system 340 illustrated in the cooling module 326 in the form of Figure 11. Therefore, the thermoelectric cooling system 340 illustrated in Figure 13 will employ the same reference numbers as in Figure 11, and the operation of the thermoelectric cooling system 340 will not be explained again in detail in relation to Figure 13. Cooled air flowing through the compartment 366 it can carry heat released by the heat sink housing 346 to the central cooling unit 60. Thus, compartment 367 can be cooled regardless of the temperature in compartment 366, based on the temperature selected for compartment 367 by the temperature selector 86 for compartment 366. Also, as described above, the thermoelectric cooling system 340 can provide temperatures of lower storage in compartment 367 than can be efficiently obtained in compartment 366 based on the cooling provided by the cooled air. Although the cooling module 360 illustrated in Figure 13 does not include air passages through compartment separator 365 to allow cool air to flow to compartment 367, those skilled in the art will understand that the appropriate air passages and deflectors, all not shown, they can be provided in the compartment separator 365 for the provision of the possibility of selective cooling of the compartment 367 using cooled air or a cooling through the thermoelectric cooling system 340.

Controller 396 can control the operation of cooling appliance 384, as is well known in the art, and can include a connection to controller 50 for central cooling unit 10. The 384 household refrigeration appliance can efficiently provide much colder cooling temperatures than can be achieved in a practical way using a cooled liquid refrigerant supplied by the central cooling unit 10, since the compression compression cascade cooling unit steam 400 can efficiently provide temperatures below 0 ° C. Although a vapor compression cascade cooling unit 400 is illustrated in the form of Figure 15, those skilled in the art will understand that a thermo-electric cooling unit or a Stirling cycle cooling unit, as illustrated in Figures 17A and 17B below, can be used as desired.

As mentioned above, the cooling module 350 'can be similar to the cooling module 350 in the form of Figure 12, with the exception of the heat exchanger and the connection of the thermoelectric cooling system 340 to the central cooling system 10.

Central cooling unit 402 can be a Stirling cycle cooling unit that may include a Stirling cycle cooler 404 which may have a hot end 410 and a cold end 413, as is well known in the art. The Stirling 404 cycle cooler can have a 406 linear motor and can have a hot end heat exchanger 411 and a fan 412 for heat rejection of the hot end 410. The cold end 413 can be associated with a cooled liquid cooler 415 which can be arranged for heat transfer from the cooled liquid in the cooled liquid circuit to the cold end 413.

The Stirling cycle cooler 404, fan 412 and pump 44 can be connected to the controller 50 through control circuit 56. For cooling provision, the Stirling 404 cycle cooler, fan 412 and pump 44 can be activated by controller 50, causing the Stirling 404 cycle cooler to cause cold end 413 to become cold by absorbing heat in the cooled liquid cooler 415 from the cooled liquid circulated by the pump 44 and reject heat at the hot end 410 to the heat exchanger 411, as is well known in the art. Thus, as illustrated in Figures 12, 13, 14 and 16, a variety of central cooling units can be used in combination with one or more cooling modules including a cascade cooling arrangement. The central cooling units can be a vapor compression refrigeration system, a vapor compression refrigeration system with a secondary loop of cooled liquid, an absorption system or a Stirling cycle cooler with a secondary loop of cooled liquid and can be a vapor compression cooling system, an absorption system or a Stirling cycle cooler arranged to cool the air for circulation to the cooling modules having the cascade cooling arrangement.

The cooling module 20 is described in detail above and, therefore, will not be described in detail again in relation to Figure 17A. Similarly, the central cooling unit 10 is described in detail above and, therefore, will not be described in detail again in relation to Figure 17A. The cooling module 420 may include a cascade cooling system. The cooling module 420 can have an insulated cabinet 422 and insulated doors 424 and 425 that can be hinged to the insulated cabinet 422 for the selective opening and closing of compartments 426 and 427 formed in insulated cabinet 422 by the insulated compartment separator 423 Insulated doors 424 and 425 can be provided with a suitable handle, not shown, to facilitate the opening and closing of insulated doors 424 and 425.

430, allowing the 430 cascade cooling system to function at a much higher capacity than a similar system having a room air-cooled condenser. Thus, compartment 427 can be cooled regardless of the temperature in compartment 426, based on the temperature selected for compartment 427 by the temperature selector 36 for compartment 427. In addition, as described above, the vapor compression cascade cooling system 430 can efficiently provide much lower storage temperatures in compartment 427 than can be obtained in compartment 426 based on the cooling provided by the cooled liquid refrigerant.

The central cooling unit can be similar to the central cooling unit 10 illustrated in Figure 1 and, therefore, will use the same reference numbers as the central cooling unit 10 illustrated in Figure 1. Similarly, the cooling module 20 can be similar to the cooling module 20 illustrated in Figure 12 and, therefore, will use the same reference numbers as the cooling module 20 in Figure 12.

Similarly, the central cooling unit 10 is described in detail above and, therefore, will not be described in detail again in relation to Figure 17B. Cooling module 440 may include a cascade cooling system. The cooling module 440 may have an insulated cabinet 442 and insulated doors 444 and 445 that can be hinged to the insulated cabinet 442 for the selective opening and closing of compartments 446 and 447 formed in insulated cabinet 442 by the insulated compartment separator 443 Insulated doors 444 and 445 can be provided with a suitable handle, not shown, to facilitate the opening and closing of insulated doors 444 and 445.

A loop 42 can transport the cooled liquid cooler leaving the evaporator 30 to the hot end 455 to remove heat from the Stirling cycle cooler, allowing the cascade cooling system 450 to efficiently cool compartment 447. Thus, compartment 447 can be cooled regardless of the temperature in compartment 446, based on the temperature selected for compartment 447 by the temperature selector 36 for compartment 447. In addition, as described above, the vapor compression cascade cooling system 430 can efficiently provide much lower storage temperatures in compartment 447 than can be obtained in compartment 446 based on the cooling provided by the cooled liquid refrigerant.

The cooling / storage module 460 can be selectively operated as a refrigerated storage space, when the circulation fan 465 is operated by controller 150 (Figures 3 and 6). Alternatively, the circulation fan 465 can be deactivated and the cooling / storage module 460 can be allowed to remain at room temperature in the location in which it is positioned. The 465 circulation fan can be a variable speed fan, or a single speed fan that can be turned on and off in cycles to control the temperature in the 460 cooling / storage module.

Cooling module 120 is described in detail above and, therefore, will not be described in detail again in relation to Figures 18 and 19. Cooling / storage module 472 may be located in the vicinity of cooling module 120 and may be connected to the cooling module 120 by an isolated supply duct 216 and an isolated return duct 218 similar to the combined satellite station 240 illustrated in Figure 8A.

Similarly, two cooling / storage modules 460 could be provided for a cooling module 120 or 466, since circulating fans 465 could provide adequate cooling air circulation in at least two cooling / storage modules . Thus, in the embodiment of the invention illustrated in Figures 18 and 19, a distributed home appliance system can have one or more cooling / storage modules to allow for additional temporary refrigerated storage space that, when not needed, could be converted in a storage space at room temperature. Those skilled in the art will understand that a second damper, not shown, can be provided for the isolated return duct 218 to prevent cool air from flowing into the cooling / storage module 460 or 472, when the user has deactivated the cooling fan. circulation 465 and / or closed the damper 476 to operate one or more cooling / storage modules as a storage space at room temperature.

Refrigeration module 120 can be independent or built-in modules and can be a general purpose, freezer or special purpose refrigerator module, and can be located in a residential kitchen or other locations associated with a home, as desired. The cooling module 120 can be similar to the cooling module 120 illustrated in Figure 3 and, therefore, will use the same reference numbers as the cooling module 120 in Figure 3. Alternatively, the cooling module could also be similar to the combined satellite station 240 shown in Figure 8A. Central cooling unit 110, additional satellite stations 212 and other home appliance refrigeration modules have not been included in Figure 20 for simplification of the drawings. The isolated supply lines 142 and the isolated return lines 144 (see Figures 3 and 6) can be connected to the quick-connect connections 145 to provide a refrigerant circuit for the evaporator 130 in the cooling module 120 from a central cooling unit 110 (see Figures 3 and 6). As noted above, the central cooling unit 110 may be located in a remote location of a residential kitchen, or in or in the vicinity of a residential kitchen, as desired, as those skilled in the art will understand.

The cooling / storage module 478 can also have a selector 482 which can be a switch connected to the control circuit 156. In some embodiments of the invention, the cooling / storage module can comprise an isolated insert in a cabinet, as will be described in further details below. In these circumstances, it may be advantageous to provide a selector switch 482 to indicate the presence or absence of an isolated insert for the formation of the insulated case 479, to avoid operating the cooling / storage module 478 at temperatures below ambient without the insertion of insulation in place. Those skilled in the art will understand that the selector switch can be arranged to be manually adjusted by a user, or it can be automatically closed to indicate the presence of an isolated insert when positioning the isolated insert in the cabinet. The cooling module 120 and the cooling / storage module 478 can have temperature sensors 134, as described above, and can have temperature selectors 136, not shown, which can be combined with the respective cabinets or can be part of an interface central user as described above. Temperature sensors 134 and temperature selectors 136 can be connected to controller 150 (Figures 3 and 6) via control circuit 156.

Alternatively, the damper 486 can be positioned to block the flow of cooled air from the cooling module 120, and the cooling / storage module 478 can be allowed to remain at room temperature in the location in which it is positioned. Those skilled in the art will understand that the isolated return duct 218 can also be provided with a damper, not shown, to help ensure that the cooled air does not flow from the cooling module 120, when the user wishes to allow the cooling module refrigeration / storage77 remains at room temperature for additional storage space. The cooling / storage module 478 can also have a heating element 484 that can be arranged to heat the contents of the cooling / storage module above room temperature. The heating element 484 can be connected via the control circuit 156 to the controller 150 for selective operation of the heating element 484. The use of a heating element 484 can allow a user to select a cycle to give a temperature sequence for the contents of the cooling / storage module 478, which may include heating the contents to a temperature above room temperature, as will be described in details below. Thus, in the embodiment of the invention illustrated in Figure 20, a distributed household refrigeration appliance system can have one or more cooling / storage modules to allow for an additional temporary refrigerated storage space that, when not needed, can be converted to a storage space at room temperature, or it can be operated to provide one or more predetermined temperature sequence cycles for handling the contents of compartment 481.

As mentioned above, the 570 refrigeration unit can have a top-mounted freezer compartment and a top-mounted freezer compartment at the bottom opposite the 494 cooling / storage module. The 486 damper can be manually adjusted by the user, or it can be an automatic damper, as described above, to control the amount of cooled air flowing to the 494 cooling / storage module, and therefore the operating temperature. In the modality illustrated in Figure 22, a circulation fan 457 can be provided in the isolated return duct 218, to guarantee a circulation of cooled air, see the air flow arrows 148, for the cooling / storage module 494 from from the independent cooling appliance 570 and back to the independent cooling appliance 570.

In the modality illustrated in Figure 23A, the independent refrigeration appliance 570 may be similar to the satellite station / combined appliance refrigeration appliance / central cooling unit 282, not shown, (see Figure 10). The cooling module 466 is described above in detail in relation to Figure 18 and, therefore, will not be described again in detail, again, in relation to Figure 23A. The cooling module 466 can be positioned in a lower cabinet 489, as shown in Figures 21 to 22. The cooling / storage module 496 can be positioned adjacent to the cooling module 466 and can be connected to the cooling module 466 via the insulated supply duct 216 and the isolated return duct 218 and can have a circulation fan 465 associated with the duct insulated supply 216 for cooling air circulation from cooling module 466 to compartment 499, when circulation fan 465 is operated.

The secondary cooling medium circuit may include a heat exchanger 512 which can be positioned in compartment 308 in the vicinity of evaporator 320 for rejection of heat from insulated compartment 491 to compartment 308 and evaporator 320. Heat exchanger 512 can be connected with insulated ducts 42 to the alveolar 513, which can be positioned in the insulated cabinet 491 and a pump 514. Pump 514 is illustrated as being positioned in an isolated compartment 491, although pump 514 can be positioned in other locations, if desired, including in the central cooling unit space 311, as desired. As described above, the liquid coolant for the secondary cooling medium circuit, not shown, can be a DYNALENE HC heat transfer fluid, a water-based organic salt that is non-toxic, non-flammable with low viscosity, or other liquid coolant solutions, such as a solution of ethylene glycol and water. In operation, when a user chooses to operate the cooling / storage module as a refrigerated space, selector switch 482 can be closed and pump 514 can operate under the control of controller 300 and a temperature sensor 134, not shown, to circulation of the liquid cooler through the front target 513 to cool the insulated cabinet 491. In order to operate the cooling / storage module 492 'as an unconditioned storage space, the selector switch 482 can be opened and the pump 514 de-energized to allow the temperature in the insulated cabinet 491 to rise to room temperature. The insulated cabinet 491 can be a container forming a space for holding a liquid or paste material, such as water or ice cream or other liquid, semi-liquid or paste materials that a user could choose to cool or cool for use, or as a step in preparation. Insulated cabinet 491 could take the form of an insulated tank or container, or it could be an insulated space arranged to receive a container of liquid and / or removable paste, not shown. The front target 513 can be positioned to cool a removable liquid / paste container, not shown. Those skilled in the art will understand that modules other than the cooling / storage module 492 'may comprise, or be arranged to receive, a tank or container for storing and / or cooling a liquid or paste material, if desired. Similarly, the cooling / storage module 492 'can be used in combination with the satellite stations, as illustrated in the modalities of Figures 6 to 11, as desired.

Those skilled in the art will understand that the independent refrigeration appliance 570 can be configured as a bottom freezer appliance having an evaporator at the bottom of the appliance and that, therefore, the refrigeration / storage modules 492, 492 'and 494 they could be switched to correspond to the freezing compartments above and the freezing compartments below in the 570 independent refrigeration appliance. In addition, although heating elements have been illustrated in the cooling / storage modules 478 and 496, those skilled in the art will understand that the heating elements could be provided in any of the cooling / storage modules illustrated in Figures 18, 19, 21 or 22. Thus, in the embodiment of the invention illustrated in Figures 21 to 23B, a distributed refrigeration appliance system may have one or more cooling / storage modules combined with an independent refrigeration appliance to allow for an additional temporary refrigerated storage space that , when not needed, can be converted to a storage space at room temperature or, if provided with a heating element, can be used to heat contents to temperatures above ambient.

The insulated cabinets described above can be formed of wood, metal or molded plastic and provided with an insulating material, such as polyurethane foam or expanded Styrofoam, as is well known in the art. Also, as is well known in the art, these insulated cabinets can be formed at a manufacturing location and shipped to a service location in the final form, or can be manufactured at the service location by cutting and assembling the cabinets from of insulated panels and preformed insulated doors. According to the invention, an insulated cabinet and an insulated door for a cooling / storage module can be formed by providing an insulated insert and an insulated door kit for converting a non-insulated cabinet into a cooling / storage module . Turning to Figure 24, which includes an exploded view of an isolated insert 500, the preparation of an isolated insert 500 can be seen. The insulated insert 500 can include an insulated box 502 and an insulated door 504 that can be attached to the insulated box by hinges 510. The insulated door can include a handle 511 to facilitate the opening and closing of the insulated door 504. The insulated box 502 may include an insulated back wall 505, an insulated top wall 506, an insulated back wall 507, an insulated left side wall 508 θ and an insulated right side wall 509, which can be mounted on insulated box 502, as is well-known in the cabinet industry. The insulated insert 500 can be inserted in an upper case 488 or a lower case 489 for converting a conventional case into a cooling / storage module. Those skilled in the art will understand that, instead of manufacturing the insulated insert 500 as an insert, an insulated case can be manufactured, which can replace an upper case 488 or a lower case 489, if desired. If an insulated cabinet is to be built instead of an insulated insert, panels having an acceptable external surface can be used in combination with other cabinets used in the home, as needed. In accordance with this aspect of the invention, distributed cooling modules can be provided to meet the requirements for the cooling system by the intended user, without requiring the user to conform to module sizes generally available in the mass market for household appliances. cooling. The construction described above for the insulated insert 500 can be used for any of the cooling / storage modules 460, 472, 492, 492 ', 494 and 496 described above, if desired.

Turning to the schematic Figures 25 and 26, in another embodiment of the invention, a refrigeration appliance 570 can be combined with a refrigeration / storage module that can be arranged for the selective provision of a refrigerated storage or storage space. additional non-conditioning above or below the 570 refrigeration unit. The refrigeration appliance 570 can be a built-in or independent appliance and can be positioned in a kitchen or in another location in a home in relation to upper cabinets 488 and lower cabinets 489. The refrigeration unit 570 can be similar to a satellite station / home appliance refrigeration module / central cooling unit combined 282, as illustrated and described in Figure 10, or it can be similar to a conventional freezer and refrigerator. The refrigeration appliance 570 will not be described again in detail in relation to Figures 25 and 26.

In Figure 25, the refrigeration unit 570 can be installed on or above a refrigeration / storage module 515 for lifting the refrigeration unit 570 to facilitate user access to the lower compartment of the refrigeration unit 570, without having to flex unduly. The cooling / storage module 515 may include an insulated cabinet 516, an insulated door 517, and, if desired, a selector 482, as described above. The cooling / storage module 515 can have a temperature sensor 134, a temperature selector 136, not shown, and a diffuser 518 that can cooperate with insulated ducts 519 by connecting the cooling / storage module 515 to the bottom compartment 310 of the appliance. cooling 570. Insulated duct 519 can be a concentric duct or it can be a parallel two-pass duct to provide a supply and return passage for the cooling / storage module 515. Temperature sensor 134 and temperature selector 136, not shown, can be connected to controller 300 (Figure 10) through control circuit 306. Insulated door 517 may have a handle, not shown, to facilitate access to the cooling / storage module 515. Insulated duct 519 may have a damper 486 to selectively allow air cooled from the refrigeration apparatus 570 to flow to the cooling / storage module 515. A circulation fan 523 can ensure that the air cooled from the cooling module refrigeration / storage 515 return to compartment 310 of refrigeration appliance 570. As described above in detail, the cooling / storage module 515 can be selectively operated as a cooled storage space by positioning the damper 486, to allow cool air to flow through the insulated duct 519 and the operation of the circulation fan 523 As above, the damper 486 can be manually operated by a user can be an automatic damper connected to controller 300 (see Figure 10) via control circuit 306. The circulation fan 523 can be connected through control circuit 306 to controller 300 and can be operated when a user selects a refrigerated operation from the 515 cooling / storage module. Likewise, as described above in relation to other modalities, a user can allow the 515 cooling / storage module to reach room temperature with the damper 486 positioned to block the cooled air flow to the 515 cooling / storage module and circulation fan 523 de-energized.

Turning to Figure 26, the cooling / storage module 520 can be positioned above the cooling device 570 in the space between the top of the cooling device 570 and a soffit or the ceiling at the location in the dwelling in which the cooling device 570 is located. The cooling / storage module 520 can include an insulated cabinet 521 and an insulated door 522 that can be hinged to the insulated cabinet 521. The insulated door 522 may have a handle, not shown, to facilitate the opening and closing of the insulated door 522. In Figure 26, the insulated door 522 is illustrated schematically as pivoting on a horizontal geometric axis. Those skilled in the art will understand that insulated door 522 can be hinged to pivot on a vertical geometric axis similar to insulated door 517 in Figure 25, if desired. The cooling / storage module 520 may have a selector 482, as described above, and may have a temperature sensor 134 and a temperature selector 136, not shown. Temperature sensor 134 and temperature selector 136, not shown, can be connected to controller 300 (Figure 10) via control circuit 306. An insulated supply duct 216 and an insulated return duct 218 can connect the cooling / storage module 520 to the refrigeration unit 570. Insulated supply and return ducts 216 and 218 can have a damper 486 for controlling air flow cooled from the cooling device 570 to the cooling / storage module 520 and back to the cooling device 570. As described above, the 570 can be a satellite station / the combined home appliance refrigeration module / central cooling unit 282 (see Figure 10) which can include an evaporator fan 322 (see Figure

10). The evaporator fan 322 can circulate the cooled air through the isolated supply ducts 216 and return 218 when the dampers 486 are positioned to allow air to flow through the ducts. The 486 dampers can be manually adjustable by a user to allow the cooled air to flow to a sufficient volume to maintain a desired temperature in the cooling / storage module 520, or they can be automatic dampers that can be connected to a controller 300, not shown, for temperature control in the cooling / storage module 520, based on an input from a temperature sensor 134 and a temperature selector, both not shown. Thus, in Figures 25 and 26, the refrigeration / storage modules 515 and 520 can be combined with a refrigeration appliance 570 that can be selectively operated as a refrigerated or ambient storage space, to allow a user to have a storage space. refrigerated storage or at additional room temperature, as needs change.

As described in relation to Figures 20 and 23, a cooling / storage module may have a heating element 484 to allow a user to selectively raise the temperature in the module above room temperature, as well as to cool the module below room temperatures . In each mode, the cooling / storage module can have a flow controller to allow or block the flow of cooled air to the cooling / storage module and, as in the modalities illustrated in Figures 20 and 23, it can have a heating element that can be selectively energized to heat the contents of the cooling / storage module. The flow controller, damper 486 or circulation fan 465, and heating element 484 can be connected to controller 300 (see Figure 10) via control circuit 306. System controller 300 may be arranged to selectively operate at least one flow controller to allow cool air to flow through at least one insulated duct for cooling the contents of the cooling / storage module to a temperature below the desired environment ; or selectively operating the flow controller to block the flow of cooled air through at least one insulated duct for operating the cooling / storage module as an unconditioned storage space (i.e., at room temperature); or selectively operating the flow controller to block the flow of cooled air through at least one insulated duct and selectively operating the heating element to heat the contents of the cooling / storage module to a desired temperature above ambient; or selectively operate the flow controller approximately to allow or block the flow of chilled air to the cooling / storage module and selectively operating the heating element to sequence the storage temperature of the contents in the cooling / storage module through a sequence cycle predetermined temperature to cause physical or chemical effects on the contents of the cooling / storage module. For example, predetermined temperature sequence cycles may include defrosting, fermenting, leavening, rapid-setting cooling and rapid cooling.

Turning to Figures 27A to 27D, an illustration of time and temperature conditions in four temperature sequence cycles can be seen. In Figure 27A, controller 300 can be programmed to cause the temperature in a cooling / storage module to rise to a predetermined regulated temperature to leaven the contents and then hold for a predetermined time or with an open end. In Figure 27B, controller 300 can be programmed to maintain the contents of the refrigeration / storage module at a regulated temperature above the predetermined environment for a predetermined time for aging or fermentation of the contents and then to reduce the temperature of the contents to a temperature maintenance, which may be above or below ambient temperature. At 27C, controller 300 can raise the temperature to defrost the contents and then maintain the contents at a reduced temperature above freezing. In Figure 27D, the controller can cause the temperature in the cooling / storage module to rapidly drop to cool the contents and then allow the temperature to rise to a regulated temperature. In the programs illustrated in Figures 27B,

27C and 27D, the controller can be arranged to switch from higher to lower temperatures or from lower to higher temperatures, based on an elapsed time, or an input from a temperature sensor or another sensor, such as a moisture, carbon dioxide or hydrocarbon sensor (such as ethylene or other food product gases caused by ripening or decay), so that the predetermined temperature sequence cycle is dependent on the changed condition / condition of the contents of the cooling / storage module. Those skilled in the art will understand that predetermined temperature sequence cycles, in addition to those illustrated in

Figure 27 and described above, can be used with the cooling / storage modules described above. Likewise, those skilled in the art will understand that a controller can be arranged to allow a user to program a temperature sequence cycle using a user interface or another well-known programming method20.

Turning to Figures 28 and 29, a cooling system distributed according to the installed invention applied to a floor level of the house can be seen schematically. Residential housing 525 illustrated in Figures 28 and 29 may have a kitchen 526, a bathroom 528, an office or small work room 520, a living room or family room 532 and a patio 534. Although a refrigeration system distributed according to the invention is illustrated in a simple housing in Figures 28 and 29, those skilled in the art will understand that refrigeration systems distributed according to the invention can be used in combination with any housing style having any desired number of rooms or floor levels. The distributed cooling system illustrated in Figures 28 and 29 can have a primary cooling machine, a central cooling unit 10, which can be similar to the central cooling unit 10 illustrated and described in detail in relation to Figures 1, 12, 15 , 17A and 17B and will not be described again in detail in relation to Figures 28 and 29. The central cooling unit 10 can include a controller 50 and can have temperature selectors 36 which can be located on a user interface in a remote location, such as in kitchen 526, as shown in Figures 28 and 29. Although temperature selectors 36 are illustrated in a combined user interface, those skilled in the art will understand that temperature selectors 36 can be combined with each remote cooling device, if desired, as is well known in the art. The central cooling unit 10 can be connected to a secondary cooling medium circuit. In the embodiment illustrated in Figure 28, a secondary cooling medium circuit comprises an insulated conduit 42 that forms a loop leading from the cooled liquid evaporator 40 in the central cooling unit 10 around the perimeter of the drive piston head.

525 and back to the cooled liquid evaporator 40. As described in detail above, the pump 44 can circulate a liquid cooler through insulated ducts 42. Although insulated duct 42 is positioned on the perimeter walls in Figures 28 and 29, those skilled in the art will understand that insulated ducts 42 can be located on other walls and / or portions of the home, as desired, to provide access to the loop secondary cooling in desired locations in the house. A pressure differential valve 541 can be provided in the secondary cooling medium circuit to adjust any pressure differential between supply and return pressures. The secondary cooling medium circuit, also referred to as the secondary cooling loop, can include a plurality of access points 535 (Figure 28) and 535 '(Figure 29). An enlarged view of an access point 535 can be seen in Figure 28A. Access point 535 can include a housing 533 which can wrap around conduits 42 and can support remote device connectors 543 when a remote cooling device is connected to an access point. Remote device connectors 543 can be well-known connectors for use with liquid refrigerant circuits and can be quick-connect or permanent connections, as desired. Access point 535 may also include an electrical connector, not shown, for making a suitable connection between control circuit 56 and the electrical component (s) in the remote cooling device. Access point 535 can also include a valve 545 that can be connected to control circuit 56. Valve 545 can open to allow cooled liquid refrigerant to flow to a remote cooling device when activated by controller 50. Although a central cooling unit 10 is shown in Figures 28 and 29, those skilled in the art will understand that a central absorption cooling unit, as shown in Figure 14, or a central Stirling cycle cooling unit, as shown in Figure 16, can be used in the modalities of Figures 28 and 29, as desired.

A variety of remote cooling devices can be connected to the secondary cooling medium circuit for the provision of distributed cooling for various purposes in spaced locations in a home. The following are examples of remote cooling devices that can be used. Those skilled in the art will understand that the following examples are just that and that the examples are not to be understood as limiting the invention to the remote cooling devices illustrated in Figures 28 and 29. A remote cooling device can be a located cooling module 20 in a patio 534. Cooling module 20 can be a patio cooler for chilled drinks or snacks. The cooling module 20 can be similar to the cooling module 20 described in relation to Figures 1, 12, 14, 16, 17A and 17B, and will not be described again in relation to Figures 28 and 29. The cooling module 20 can be connected to an access point 535 and 535 ', as described above, and can operate as described above. Another remote cooling device can be a 384 cooling module combined with a cascade cooling unit 400. Cooling module 384 and cascading cooling unit 400 may be similar to cooling module 384 and cascading cooling unit 400 described in detail with reference to Figure 15, and will not be described again in detail. The cascade cooling unit 400 can be connected with remote device connectors to the access point 535 and 535 'and can operate as described above in relation to Figure 15. Another remote cooling device can be a dehumidifier 546 that can be used to reduce humidity in the bathroom 528 that can be generated during showers or baths. The dehumidifier 546 may be similar to the cooling modules described above and may include a heat exchanger 548, a heat exchange fan 549, a temperature sensor 34 and a humidity meter 547. The heat exchange fan 549, temperature sensor 34 and humidity meter 547 can be connected to insulated ducts 42 at access point 535 and 535 'using remote device connectors 543, as described above. Dehumidifier 546 may have a condensate basket, not shown, or it may be connected to a drain for condensate disposal, as is well known in the art. Instead of connecting the temperature sensor 34 and the humidity meter 547 to the controller 50, a control panel, not shown, can be provided in the dehumidifier 546, as will be readily understood by those skilled in the art. Another remote cooling device can be a 552 CPU cooler that can be arranged for cooling a computer's central processor or server. The CPU cooler can include a 5534 heat exchanger and a temperature sensor 34. The CPU cooler 552 can connect to the secondary cooling medium circuit using remote device connectors 543 to connect to an access point 535 and 535 '. Temperature sensor 34 can connect to controller 50 via a suitable electrical connector on control circuit 56 at the access point

535 and 535 '. Another remote cooling device can be a local area cooler 556 which is illustrated in the living room or family room 532. The local area cooler 556 can provide air conditioning or supplemental air conditioning for a room or portion of housing 525. For example, house 525 may be located in a climate that does not require air conditioning for the entire house or central, but cooling for part of a day or part of the year can be satisfactorily considered with a local area cooler 556, instead of a roomy air conditioner. The local area cooler 556 can have a cabinet 557 that can involve a heat exchanger 558 and a heat exchange fan 560. The local area cooler 556 can include a temperature sensor 34 and a temperature selector 36 that can be connected to controller 50, or alternatively can be accessed from a control panel in cabinet 557 to control the local area cooler 556 on the device. The local area cooler 556 can be connected to access point 535, 535 'using remote device connectors 543, as described above. The 556 local area cooler can operate similarly to a room air conditioner and can include a condensate collector for condensate collection, or it can have a condensate drain line that can be connected to a home drain line or can be directed outside for disposal as desired.

A second primary cooling machine can be connected to the secondary cooling loop to provide an additional source of cooling in the secondary cooling medium circuit. In the embodiment illustrated in Figures 28 and 29, the second primary refrigeration machine can be a 536 horizontal freezer. The horizontal freezer 536 may have an insulated cabinet 537 and a freezer cooling circuit including a static evaporator 538, an expansion device 539, a condenser 540, a compressor 542 and a condenser fan 550. The horizontal freezer 536 can also have a heat rejection element which can be a cooled liquid evaporator 544 which can be connected to insulated ducts 42 at an access point 535, 535 'using remote device connectors 543 which can provide additional cooling in the secondary cooling loop. The horizontal freezer 536 can also have a temperature sensor 34 and a temperature selector 36 that can be connected to controller 50 via control circuit 56, as described above. Those skilled in the art will understand that the horizontal freezer 536 can have a suitable cover or insulated housing, not shown, and that the temperature selector 36 can be positioned on a control panel in the horizontal freezer 536, if desired, rather than on a remote user interface as illustrated. When the horizontal freezer 536 is operating, a suction line heat exchanger or chilled liquid evaporator 544 can absorb heat from the liquid cooler being circulated in the insulated ducts 42, thereby supplementing the cooling capacity of the distributed cooling system. . In addition, the freezer cooling circuit may include a bypass valve 551 that can be integrated with the expansion device 539 connected to the control circuit 56, which can allow a central controller 50 for the bypass evaporator 538 make the cooling capacity of the horizontal freezer 536 available on the cooled liquid evaporator 544 to provide additional cooling for the distributed cooling system. Although a secondary primary refrigeration machine is illustrated as a horizontal freezer in the modalities of Figures 28 and 29, those skilled in the art will understand that other refrigeration machines, such as a central air conditioner condensing unit, freezers of other configurations, as well as such as refrigerator freezers, ice makers, air-conditioned cellars and the like having a cooling unit, can be used as an additional primary cooling machine in a distributed cooling system, if desired.

In the embodiment illustrated in Figure 29 and Figure 29A, the secondary cooling medium circuit can have a single insulated conduit 42 connecting access points 535 'to the cooled liquid evaporator 40 and pump 44. Access points 535' can have a housing 564 and may include a valve 566 that can be connected to controller 50 via control circuit 56. Valve 566 can close, forcing the cooling of cooled liquid circulating in the insulated conduit 42 to bypass through the remote device, when valve 566 is closed by controller 50. Access point 535 'may have a suitable electrical connector, not shown, for easy connection of remote cooling devices to controller 50. The secondary single-line cooling medium circuit shown in Figure 29, otherwise, it can operate similarly to the supply line and return line system illustrated in Figure 28.

The cooling modules, cooling / storage modules, satellite stations, combined satellite stations and central cooling units described above were selected to explain the invention. However, the invention is not limited to specific examples of modules, satellite stations and central cooling units, and these elements can take any desired shape and can be combined as desired within the scope of the invention. The invention is not to be limited to refrigeration modules and equipment located in any particular geometric orientation. The central cooling unit and receiving modules do not need to be positioned in the same horizontal plane, as appropriate pumps and fans can adjust elevation differences resulting from a desired location of cooling units and modules. Although the use of quick coupling connections for connecting satellite stations to refrigerant lines in distributed refrigeration systems is described above, those skilled in the art will understand that quick coupling connections are not necessary for the practice of the inventions described in this application and that, instead, any well-known refrigerant line connection arrangements can be used as desired.

The controllers for the central cooling units, the cooling modules, the satellite stations, the combined satellite stations and the central cooling units and the cooling / storage modules described above, including the control circuits, the thermostats, the selectors temperature switches and selector switches, can be arranged to function as controls, components and devices to connect and use, or they may be arranged to function as part of a home appliance network that may be part of a home network.
